Preparation and performance of a high purity poly-aluminum ...
This study examines the possibility of using Polyaluminum Chloride (PACl) instead of Aluminum Sulphate (Alum) as a coagulant in surface water treatment process and compares between both coagulants at actual parameters ranges (Turbidity, pH, Temperature, and Residual Chlorine). The results indicated PACl is performing better than Alum.

The BSF process improves the sedimentation speed and overflow rate, reduces the footprint of the system, and greatly reduces the cost of coagulation treatment. Many researchers have conducted in-depth research. For example, Desjardins 17 conducted comparative experiments in three different water treatment plants, and the results showed that the amount of coagulant was the key parameter that ...

In the case of surface water, pre-treatment such as coagulation, sedimentation and filtration is generally used to prepare the water before its final disinfection. Hence, apt protective measures and management of raw water reservoirs are capable of minimising need for chemical disinfection of the drinking water.

Get PriceWhy is polyaluminum chloride a good coagulant for water treatment?
Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .
Does polyaluminium chloride coagulant affect the structure and diversity of pollutants?
The polyaluminium chloride (PAC) coagulant was applied to determine the impact of the treatment process on the structure and diversity of these pollutants in urban drinking water.
What is high-purity poly-aluminum chloride (PACL)?
Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high–purity PACl are needed.
What is the coagulation time for aluminum sulfate and aluminum chloride coagulants?
However, for aluminum sulfate and aluminum chloride coagulants the coagulation time and settling time were reached to 15 and 35 min, respectively. The results revealed that the residual aluminum concentration in the treated water was very small for synthesized PAC coagulant which was <0.2 mg L −1.
Does high-purity PACL remove turbidity?
Samples taken from the Huangpu River were used to evaluate the coagulation performance of high-purity PACl in comparison with conventional PACl. The results demonstrate that for the whole dose range studied, high-purity PACls removed more turbidity than conventional PACl.
Can coagulation remove pollutants from urban drinking water?
Conclusions In this study, the coagulation method, which is simple and cost-efficient, is proven as an effective process to remove pollutants from urban drinking water. Although several coagulants have been experimented with for urban drinking water treatment, the PAC coagulant was investigated as efficient for TOC, TSS, and TN removal.
